I have followed the MSDN article on creating an item template for VS 2012. My template shows up on the file/new projects. Great.
I also followed the article on creating the VSIX project so I can eventually upload the template to the online gallery (I have the same templates online for VS 2010).
However when I double-click the vsix file, I get a VSIX Installer error:
"The InstalledByMSI element in extension xxx cannot be 'tru' when installing an extension through the Extensions and Updates Installer. The element can only be 'true' when an MSI lays down the extension manifest file."
I can find no setting to change this in my VSIX project. So I resorted to using 7zip to extract all the files in the vsix (zip) file. I then edited the extension.vsix manifest file and set the value to 'false'. I used 7zip to zip the files up and changed the extension to vsix.
Now when I try to install, I am told it is an invalid vsix file.
How do I use the vsix project to correctly package up the item template I want to deploy to the online gallery?
